OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Bosch 1987432190 / Febi 27465

Accuracy note: Covers the Toyota Auris (E180 2013-2018) as listed in the UK aftermarket catalogues. A cabin filter is a cheap part, but it is bought by number, and the number depends on whether your car was built with a standard particulate filter or an activated-carbon one, as well as on trim and build date. The references below are aftermarket catalogue listings for this generation, grouped by brand; the carmaker's own number is not quoted in those listings, so check the genuine filter against your VIN if you want a guaranteed match. Carbon versions carry their own numbers and are listed separately.

Cabin filter, standard (aftermarket)	Bosch 1987432190, Febi 27465, Valeo 715620, Blue Print ADT32514
Activated-carbon version (aftermarket)	Bosch 0 986 628 623, Febi 108322, Blue Print ADJ132518
Genuine (OE) number	Not quoted in the catalogue listings — the fitted filter varies by trim and build date, so order the genuine one against your VIN
Fitment notes	Standard and carbon filters have different numbers, and the right size depends on trim and build date. Check which type your car was built with before ordering.

A Genuinely Useful Diagnostic Technique Worth Trying First — Toyota Auris Cabin Air Filter

If you're chasing a musty or damp smell and have already changed the cabin filter without success, this is genuinely worth trying: switch specifically between "fresh air" and "recirculate" settings and see if the smell only appears on fresh air. If so, this points toward the external air intake area (the scuttle, at the base of the windscreen) as the genuine source rather than the filter itself. Debris can accumulate in this intake and block the drain, allowing standing water and decaying organic matter to develop a genuine, persistent musty smell that a filter change alone won't resolve.

A genuinely useful detail worth knowing about the scuttle drain's position: on some models, this drain is positioned off-centre rather than symmetrically, meaning which side of a slope the car is parked on can genuinely affect how well it drains after rain.

It's also worth knowing that a genuine, documented Technical Service Bulletin has covered cases where the metal used within the air conditioning condenser itself can generate a distinctive musty smell, with affected cars under warranty qualifying for a condenser replacement rather than simply another filter change.

Toyota Auris Cabin Air Filter: Easy to Forget, Easy to Fix

Skipping this one on a Toyota Auris won't cost you performance or reliability, only air quality inside the cabin — which is why it's routinely the most overdue item on any used car's maintenance history.

Before you buy: filter size and whether your car uses a standard or activated-carbon filter varies by trim. Always confirm against your VIN before ordering.

Toyota Auris Cabin Air Filter: What It Does

Two filters get mixed up constantly on the Toyota Auris: this one cleans air for the cabin ventilation system, catching dust, pollen and (on activated-carbon versions) some airborne pollutants, while the separate engine air filter deals purely with combustion air. They don't share a part number or a purpose.
